Actually you cant do nothing with your Sol Artina.. you cant sell.. you cant tag to another character.. etc..

To become a normal "awakening weapon" should be quest asking for boss aura, from melting weapon like black star crafting.

Then, your sol artina wont be more acount binded ..And you can sell in market.. when you tag another character, it convert to dandelion... And must have internal caphras counter even if they are useless you can extract they.
